Step 1 – Wiring
The following table shows you the necessary wires to connect from the
SP-402/502,
and what they connect to.
This chart only lays out what is needed for basic remote start operation and keyless entry. Any wires on your
remote start that are NOT listed in the table are NOT required. Security features are optional and connection
requirements will depend on your needs. For security connections, refer to
SP-402/502
owner’s manual and
your vehicle wiring chart.

NOTE 1
Some vehicles will call for a ‘+’ polarity connection to the parking light circuit and some will call for a ‘-
‘ connection. The red/black wire on the remote start is used to select the polarity of the remote start’s parking
light output. If your vehicle’s parking light wire is shown with a ‘+’ on your wiring chart, connect the red/black
wire to a co12v power source (you can tap it right on to one of the large red power input wires on the
remote start’s 6-pin harness). If your vehicle’s parking light wire is shown with a ‘-’ on your wiring chart,
connect the red/black wire to ground. The white wire in the remote start 12-pin harness is the actual parking
light output wire. After you’ve properly selected it’s polarity using the red/black wire, connect the white wire
to the parking light wire in your vehicle, as indicated on your wiring chart.
NOTE 2
The grey wire is used with a pin switch (included in your kit) to prohibit the remote start from activating
while the hood is open. This is an important safety feature!
-Before proceeding, plug the antenna, programming button, and LED into the remote start. For tips on where
to install these, see Installer’s Tip #1 .
